Gleam is nothing like Erlang or Elixir (its copying of Rust is so slavish it even has a toml file driven build system) and Erlang and Elixir are not split (the only place where they even sorta are is rebar vs. mix).
I don't particularly want to gatekeep "Rust fans who just want to write lots of Rust" off OTP. Let them have Gleam. Maybe they'll figure out how to lifetime-annotate binaries?
Gleam and Rust are really not alike at all aside from the most superficial ways. A couple bits of syntax, and the use of toml are about all I can come up with.
